wxWindows Installation

Im having problems installing wxWindows for the Borland 5.5 compiler (the free one). This is the step that is giving me trouble (the last one):

b. To build wxWindows in RELEASE mode:

cd c:\wx2\src\msw
make -f makefile.b32 FINAL=1

(if you had previously built wxWindows, you need to clean all of
the object and intermediate files. Before the above make command,
run: 'make -f makefile.b32 CLEANALL')

The problem is my system does not recognize the 'make' command. I type in "make -f makefile.b32 CLEANALL" in the promt window and it just spits "bad command or filename" back at me.

Im running Windows 98 Second Edition. Anything anyone can recommend would be helpful. Thanks in advance.
